If you put additives in, you'll also have to make sure they're compatible with all the stuff you're going to put in it (ie. acrylic, seal material, etc.), I reckon that's probably more important that the unlikely chance of spontaneous explosions.</div><div id="yui_3_16_0_1_1450423707351_3234"><br clear="none"></div><div id="yui_3_16_0_1_1450423707351_2951">Alternatively, what if you made a kind of liner that could be filled with water and save the water contacting the pressure-containing walls?
